Bishop Howe has written a longer note on the House of Bishops meeting. It is available here.
In that note, he writes:
"Bob Duncan is my friend, and Pittsburgh was my Diocese from 1972 to 1976. Bob and I have not always agreed, but we have been on the same side of most of the "issues," and I believe him to be a fearless and courageous contender for the Faith. I believe this is a very sad day for the Church, and I find myself in mourning."
